How do you reset your password for Yahoo if your alternative email is expire?

If your alternative email for resetting your Yahoo passWord has expired, you can try using your phone number linked to your account for verification. Go to the Yahoo Sign-in Helper page, enter your email address, and select "Forgot passWord?" Follow the prompts to receive a verification code via SMS. If you don't have access to either recovery option, you may need to answer security questions or try to recover your account through Yahoo's customer support.
